    Steve adds a second 512-MB 240-pin DIMM to his PC, which should bringthe total RAM in the system up to 1 GB. The PC has a Pentium 4 3.2-GHzprocessor and three 240-pin DIMM slots on the motherboard. When he turnson the PC, however, the RAM count only shows 512 MB of RAM. Which of thefollowing is most likely to be the problem?
    • A. 

      Steve failed to seat the RAM properly.

    • B. 

      Steve put DDR SDRAM in a DDR 2 slot.

    • C. 

      The CPU cannot handle 1 GB of RAM.

    • D. 

      The motherboard can use only one RAM slot at a time.
